Perfume Bottle Caps & Pumps

Start with the bottle’s exact neck finish, then match the pump, gasket, collar, cap inner structure and dip tube as one assembly. Nominal appearance or neck diameter alone does not confirm compatibility.

Approve the filled assembly for crimp or thread fit, priming, spray output, leakage, cap retention and dip-tube reach before mass production.

Dip-tube length should be matched to the internal bottle height and base shape so the tube reaches close to the bottom without being forced against the glass. A tube that is too short can leave product inaccessible; a tube that is too long can bend excessively or affect pump assembly.

Confirm the final tube length on an assembled sample and test priming and spray performance with the intended fragrance.

A crimp-neck perfume bottle uses a pump that is mechanically crimped onto the neck, usually with a collar covering the crimp area. A screw-neck bottle uses a threaded pump or closure that is screwed onto a matching neck.

The two systems require different neck specifications, pump hardware and assembly methods. Confirm the exact neck finish before selecting the pump, collar, cap and dip tube, then test spray performance and leakage on the assembled bottle.

Provide the exact container model whenever possible. If a model is not available, measure the finished opening or neck and include the dimensions that control component fit: outside and inside diameter, thread or crimp specification, rim or lid-seat geometry, relevant heights and any insertion depth.

For pumps, also provide the neck finish and required dip-tube length. For lids and stoppers, a technical drawing or physical sample is strongly preferred because nominal diameter alone does not describe threads, tapers, gaskets, inserts or fit tolerances.

In many projects, component colors and finishes can be coordinated with the bottle or jar design. The available route depends on the component material and may involve painted, plated, anodized, printed, molded-color or natural-material finishes.

Approve physical color and finish samples under consistent lighting. Metallic and natural materials can appear different from a Pantone chip or screen rendering, so the assembled bottle, jar or closure set should be the final visual reference.
